He twisted my wrist

I was experiencing how he was treated as a servant, lost in the pages of "The white tiger" sitting in the front seat of the public transport bus and suddenly a cement stained hand twisted my left wrist to see the watch, it was 10:27 am. I was shocked, I saw on my right and saw a man in his mid 20's sitting next to me, in his stained shirt, wearing earphones. I was too shocked to react, what had just happened. How can someone just twist my wrist without asking me, or may be as most of the people think, he must have thought that I was a boy and so he must have taken the liberty to touch or may be he was aware about it and he wanted to touch my wrist so he just did it. All I could manage was "aise kaise? Puch bhi sakte ho na" to which I got no response.He got down after 2 stops and the thought of him twisting my wrist remained long after that.
